Some findings:

At least 2,177 people were killed since May 1, 2013, with 1,117 of those deaths in 2014. So far, 440 people have been killed by U.S. police in 2015. Extrapolating that number would mean the total number of people killed by police would also be around 1,100 this year.

According to the data we collected, more than 105 people killed by the police this year were unarmed. Visualizing that data shows that more than 30% of black people were unarmed, about twice as many as their white counterparts.

Was the deceased armed? Black Americans killed by police are twice as likely to be unarmed as white people.

Did the deceased have any signs of mental illness?

Data shows that at least 21% of the deceased had were known to have, or had shown, signs of mental illness. This leads us to consider, was unnecessary force used in restraining suspects? Are officers properly trained to handle cases such as those?
